Nvidia Geforce 630m GPU throttling on Acer Aspire V3-571g

Hello guys, I have a problem with my new notebook that I bought. It's an Acer Aspire v3-571g with the following configuration: Intel Core i3 2350 2,3 Ghz, Nvidia Geforce 630m 2 GB dedicated, 4 GB of RAM.

The problem manifests in the following way: When the temperature reaches 75 degrees Celsius, the GPU throttles from 797 Mhz (normal frequency when on charger) to 118 Mhz for a few seconds and then to 475 Mhz. This kinda sucks because I encounter huge shuttering in games just after 2 minutes or so of playing. It just keeps going from a frequency to another all the time. Sent it to the service, they've changed the cooling system, but the problem still occurs. The tech guy from the Acer authorized service who "fixed" it told me this kind of behaviour is NORMAL. I don't think this is normal. Practically, the dedicated graphics are unusable this way! Is there any way that I can stop the throttling from occuring? It's really annoying!

From what I read all over the internet, the VGA BIOS is responsable for this throttling. Any help would be appreciated! Thanks in advance!

I had the same case with you and I thought it was crappy bios/drivers/etc. Turns out my sister's laptop just had a lot of dust in it.

Try cleaning the the fans of your laptop and check again afterwards (although I won't do this if it's still under warranty)

EDIT: I forgot about reading the part where you sent it back. So maybe it's just Nvidia Optmus acting up. Open in Nvidia control panel and set any app you want to use the Nvidia GPU ( don't use the recommended option)

I know for sure that it runs on Nvidia dedicated graphics card because I've tried running Far Cry 2 in windowed mode on 1280x720 resolution and Gpu-Z by it and when shuttering occurs the GPU frequency goes to 118 Mhz and then to 475 Mhz and there it remains for a few minutes. I don't know what's wrong and why Acer set the throttling temperature to just 75 degrees Celsius for this GPU??! This GPU's are designed to run at preety much higher temperatures (85-90 degrees Celsius). Any suggestions on how can I disable throttling on this GPU? The heatsinks are clean, the notebook arrived from service yesterday.

Tried that. The VGA BIOS is integrated in the main BIOS. Managed to extract the VGA BIOS from the main BIOS using Phoenix Tools, but Nibitor doesn't support 630m yet. I ask someone who has some knowledge in this domain: Can we get a VGA BIOS for 630m from another vendor (such as Asus) that doesn't have throttling at this temperature and flash it? Would it work?

We understand your concern and regret the inconvenience caused to you.

We would not recommend flashing the BIOS due to the inherent risk of rendering your machine inoperable.

Updated BIOS versions are made available when they offer a substantial advantage over the original installed one, or to fix specific problems reported with the original version. This means that for some products, only the original versions are available.

While newer versions may be available from other sources, Acer can not offer support on their installation or use, nor specify whether they will work properly with Acer products.

We do not provide instructions on how to update/install BIOS, as it requires experts supervision. We request you to contact a local technician, who may assist you further.

Hello! I have a weird problem with my Acer Aspire v3-571g with the following configuration: i3 2350, 630m 2 gb, 4 gb ram, 500 gb hdd. The dedicated graphics from what I see are not functioning corectlly in my opinion. The GPU seems to throttle in gaming at 75 degrees Celsius from 797 Mhz to a lower frequency (118 Mhz), then it stays at 475 Mhz. These GPU's are designed to support higher temperatures (85+ degrees Celsius), but I don't understand why it throttles at 75 degrees! Played on another Acer notebook with 540m and no throttling occurs, even after 75 degrees. Sent the notebook to service, they've changed the cooling system, but the problem still occurs. It's kind of frustrating that buying a new notebook creates so much problems! From what I've understood from the tech engineer
from "Sama Bit" (authorized Acer service in Romania) the problem is that the video BIOS is set to throttle at 75 degrees and nothing can be done. That's kind of weird and frustrating right??! With this e-mail I ask for a BIOS update for my Acer v3-571g that will fix this problem and set throttle to a more higher temperature, such as 85 degrees. Any modern GPU's run at more than 75 degrees when loaded! And I almost forgot.. It reaches 75 degrees Celsius in less than 5 minutes of gaming (World of Warcraft - medium details!) and then shutters a lot. Tried a bunch of other games and same problem. So please, can you guys post a good BIOS update to solve this issue. Thanks in advance! Waiting for an answer!

Hey man. Got some good news for ya
Go to Acer's website, then the Support section, download the latest BIOS file for your laptop model, run that .exe file, make sure you do exactly what it said. I've just updated mine, no more throttling in the GPU, a steady 797 MHz Turbo Boost GPU

Bought it from one of local city's computer store, I'm from Viet Nam btw
Well after 4 mins of Furmark, highest temp is 76 degrees, 475 MHz GPU Core. I actually noticed a funny thing, when I started Furmark, the GPU Clock Speed jumps up 797 then down to 111 then jumps right back to 475 MHz like instantly, then it stays 475 MHz in the rest of the benchmark

Yeah I have the same kind of problem, but the frequencies don't evolve that way. Mine throttles at 118 Mhz at 75 degrees for 1-2 sec and then remains at 475 Mhz. This is the last time I am buying an Acer product!

Well the thing is Acer's product is not that well-made for heavy tasking jobs like gaming, etc, ... it's for multimedia purpose and stuff like that. It's quite cheap though, since I'm running low on budget so yeah, have to use this one
At least my FPS in-game is better than before, that makes me happy enough

New Member

I'm not quite that happy. I'm not using this notebook as primary for gaming, I have a better gaming rig than this. I am just using it on a casul basis with some lite gaming such as World of Warcraft and it still shutters. Done some research, found nothing about the ability to use a VGA BIOS from other vendor than Acer. So please, can anyone tell us if we can flash a VGA BIOS from other vendor than Acer for the 630m?

I found the solution !!
Just download RW Everything, go to Embedded Controller (EC icon), and change the value like in this picture.
I found this for my laptop (Acer Aspire V3-571G-32374G50Makk) and that work pretty well !!

I can now reach the 75° limit without any throttle, and keep my max GPU frequency (800MHz) !

OP, you have a poorly designed laptop. There isn't much you can do about that other than to make sure you keep it free of dust/dirt and maybe get a decent laptop cooling fan/stand. If you override the GPU's throttle down routine in some fashion, you will likely greatly shorten its lifespan.

I change the thermal paste, and replacing it by some Artic MX5. I also clean the fan, set the fans to 100%, and use a cooling pad.
The CPU temps never reach 75°, and the GPU 80° after 2-3 hours of gaming.

I think that not too hot for a laptop. I see so many laptop at 95° CPU/GPU on gaming, so...
